Explanation of Old Faithful Linear Regression Shiny Application

Purpose

The goal of this project was to build a tool that could be used to predict how long Old Faithful was going to erupt based on the length of waiting time.

Old Faithful Geyser Data

Waiting time between eruptions and the duration of the eruption for the Old Faithful geyser in Yellowstone National Park, Wyoming, USA.

• 272 observations of waiting time(min) and eruption time(min)

Plot of Waiting Time Versus Eruption Time

As we can see below a linear model is a fairly accurate predictor of eruption time.

Model Summary

The model summary output from can be seen below.
